SPECIFICATION forming part of Letters Patent No. 708,467, datedSeptember 2, 1902.

Application filed July 18, 1901.

To 6611 whom it may concern:

Be it known that I, GEORGE H. DIMOND, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented a certain new and useful Improvement inStitched Sea1ns,.of which the following is a full, clear, and exactdescription.

In many articles of wearing-apparel, and particularly in gloves made ofleather or skin, it is of importance not only that seams be tightly andstrongly sewed, but also that they be capable of yielding or stretchingunder strain, so as to yield without breaking the stitches. Variousattempts to produce such seams have been made prior to this inventionwith more or less success. I have found a satistactory solution in aseam sewed with a single needle-thread and a single shuttle or bobbinthread, each stitch of which is triple-that is to say, in a single givenlength or stitch the thread passes forward, then backward, and thenforward in one and the same length of fabric, and then these operationsare repeated in the next advance, and so on for any length of seam, eachstitch of the triple stitch being locked.

In the accompanying drawings, illustrating my invention, in the severalfigures of which like parts are similarly designated, Figure 1 is a planview of part of a seamed fabric. Fig. 2 is a vertical longitudinalsection. Fig. 3 is a diagram of the upper or needle thread.

Obviously the drawings show the parts exaggerated.

In forminga seam in accordance with myin vention the plies of materialare overlapped, and then the article is sewed on a sewingmachine havingan upper and lower thread, preferably a lock-stitch sewing-machine, andthe needle is caused to pierce the material and its thread isinterlocked with the lower or shuttle or bobbin thread. Then the needlerises and an advance of a stitch length is made and the needle againpierces the mate- Serial No. 68,173. (No model.)

between the second and third holes, and these three lengths of needleand under threals are substantially equal to each other and 3 those laidbetween the first and second hols i.

These operations are repeated for the form tion of any desired length ofseam.

In the drawings, 1 may represent the firs.

laid stitch and 2 its lock, 3 the second stitch and 4 its lock, and 5the third stitch and 6 its lock.

7 is the first needle-hole, 8 the second, and 9 the third.

The other stitches illustrated .in the drawings are formed in similarmanner to those described.

I have found that a seam sewed in this way is very strong and at thesame time elastic and is especially adapted for use in leather or skindriving-gloves and other articles which are subjected to severe strains.

What I claim is- A stitched seam, comprising a series of stitches and afabric, such as a glove, in which said stitches are made, said seamconsisting of superposed interlocked triplets of thread of equal length.

In testimony whereof I have hereunto set my hand this 10th day of July,A. D. 1901.

GEORGE H. DIMOND.
